Growth in Ireland's domestic economy may slow to between 1.5% and 2.1% this year from an earlier forecast of 2.3% due to the inflationary impact of the war in the Middle East, Ireland's finance ministry forecast on Tuesday. Despite the downgrade, the ministry expects to run a higher budget surplus of 2.5% of modified gross national income this year, up from the 1.4% forecast in October, thanks in part to higher corporate tax income from foreign multinational firms.
